The object of my invniicm is to provirie mechanism for use win-ere twe in'teiiscking surfaces are siidably engaged and disengaged While one 0f surfaces is in mutimz such 611% the shack of su den contact i5 iessam'sd, thereby preventing ,messiva Wearing 0r grinding of said sm'fiaces and prolonging iifc of the parts.

My device is applicable in a number of ways-as, for 3113mm, in siiding gears, Siiii .ing gem and Task, (ziuzc-i' and brake mechwisms, 85s.; but i: have hem iiiusti'izted ii as awflicable to spur-gears oniy, as the mimip e is the same in all. saseii.
